I attain these objects by the mechanism illustrated in the accompanying drawings, in which:

Figure 1 is a view of my window mechanism in- Y stalled in conjunction with a conventional window .of a building, said view being taken from the inside of the conventional window, said conventional window being partially broken away to disclose the inside o! my window mechanism, one of the sash or frame members, namely the lower .one therein, being disclosed as supporting a pane of glass therein, the other or upper sash or frame member being disclosed as supporting a screen member therein; Fig. 2, a. sectional view of the window mechanism disclosed in Fig. 1, said sectional view being taken on the line 2 2, Fig. 1; Fig. 3. a rear view' of the upper sash or frame member disclosed as having been removed from the window mechanism assembly; Fig. 4, a sctional view through the upper portion .of the window sash or frame member disclosedin Fig. 3, said sectional view being takenon the line 4 4, Fig. 3, saidl sectional view being drawn to a larger scalethan that of Fig. 3: Fig. 5, a sectional view through the lower portion of the window sash or frame construction as disclosed in Fig. 3, said sectional view being taken on the line 5 5, Fig. '3, said sectional view being drawn to a larger scale than that of Fig. 3; Fig. 6, a sectional view of the window sash or frame construction disclosed in assembly with the channel or guide members which position same in the conventional window mechanism of `a building, said sectional view being taken on the line 6 6, Fig.

5; Fig. '1, a partial sectional view of the sash or f Isaid View disclosing the means for protecting. the

edge ofthe pane of glass, said means being disclosed as applied to a corner 4of the pane of glass; Fig. 12, a top view disclosing one of the ilnger or handle members assembled to a portion of one of the sash or frame members; Fig. 13, a plan view of. one of the plunger or locking members; Fig. 14, a side view of the plunger ,or locking member disclosed in Fig. 13; and Fig. 15, an

end view of the plunger or locking member disclosed in Fig. 14.

Similar numerals refer to similar parts throughout the several views.

The sash or frame construction which encloses and supports the panes of glass or the screen members in my invention are formed `with upper and lower sash or frame assemblies, Fig. 3 disclosing the upper an'd lower sash or frame as-V sembly A which comprises the end members I and 2 together with the side members 3 and 4, said sash or frame. assembly A further comprising the lower'frame assembly B, said side members 3 and 4 being disclosed as having been, adjusted to their innermost positions relative to the side portions I6 and I1 of the end members I and 2. The end member I is constructed with the channel or U-shaped structure or housing having the side anges 5 and 6 which are offset at 1 'so that said side flanges 5 and 6 will telescopically mount and slide within the side flanges 8 and 9 of the end member 2.

It is to be noted that the side flanges 8 and 9 of the end frame member I are each provided with the bent portions I5 which are Ibrought together to form a relatively small space o'r opening therebetween for receiving the pane of glass or the glass assembly II or the screen assembly I2 therein, thus providing an inwardly facing open side of U-shaped housing, the portions I5 together with the flanges 5 and 6v possessing resilient characteristics tending to close the packing members I3 to further resiliently grip and contact the glass assembly I I or the screen assembly I2 as the case may be in clamped positions, the packing or resilient members I3 being suitably secured to the inside surfaces of the side anges 5 and 6 adjacent the inside of the bent portions I5 and the inner end of the surfaces of the open side of the U shaped housing.

The packing or resilient material I3 thus resiliently clamps and positions the glass assembly I I or the screen assembly I2 in their positions in the frame assembly I, the thicknesses or the packling or resilient material I3 being sufcient to allow the bent portions I5 to slidably clearv or barely contact the sides of the glass assembly II or thescreen assembly I2.

It is to be notedthat the bent portions I5 are eachv further extended to form the overlapping flanges I4-whlch extend around the outside of the extreme inner edges or ends of the bent portions I0 of the side flanges 5 and 6,the overlapping anges Il thus tending to maintain the frame members I and 2 in their proper positions relative to a plane extending in a transverse direction, relative to the plane ofl telescopic movebeing joined together as at their corners, as indicated by the diagonal lines I8.

In a similar way the side members 3 and 4 will be provided vwithsimilar Vside flanges 5 and 6 having the bent portions I5 which will be offset Aas at I9 to allow the side flanges 5 and 6, to-

gether with the bent portions I5,to be telescopically mounted and adjustably slid within the .side flangesv and 9 of the side portions I6 and I1 of the end frame members I and 2, the

,side portions 3 and l also being further provided with the packing or resilient material I3 in a similar manner to that disclosed relative to the end frame members I and 2, in Figs. 3 and v4.

yIt is to be understood that the packing or resilient material I3 will be provided withA sufficient length ,in the various side end members of the frame constructions, together with suitable thicknesses so that the respective end and side members may telescopically move without interference with the packing materials I3 when secured and mounted in the end frame and side members and their associated members with which they are telescopically mounted.

The clip or handle members 20 are secured to the end members I and 2 by the rivets 2|, the clip-or handle members each being provided with the curved flange 22 to provide a finger or hand the operator against the flange portions 22 constituting an adjustable movement of the end members I and 2 to enable the upper frame assembly A to be moved and inserted between the channel or guide members 23 which are suitably secured to the side frame members 2l of the conventional window construction as disclosed in Figs. 1 and 2, the channel or guide members 23 extending longitudinally at the sides only of the window construction.

The clip or handle members 20 are each provided with the extension portion 36- which provides means for supporting and positioning the springs 31 between the flange portions I22, the extensions 36 extending within the coils of the springs 31, said springs 31 exerting a thrust outwardly against the anges 32 to always auto- 2,099,184 -matically force and expand the lend. members l and 2 outwardly to adiustably iii;v anyreasonable tolerances in the frame construction ofconventional windows of diiierent sizes.

The channel or guide vmembers 23 are preterabiy formed to provide .the -pair offchannels 25 and 25A which are spaced by the" portion '28 extending therebetween. The inner ends of the channel or guide members 23 are provided withthe flanges 21 which aregfolded over and carried -outwardly to a position where its edge is in a position adjacent the inner'surfaoe of the frame members 24. The outerportion of the channel onguide members 23are provided with the folded or convoluted portion 2B which is extended to form the fiange 29 which extends past and covers the outer edge 3U ofthe frame member 24, thus providing a weather strip construction which will exclude cold air, etc., from passing between the` contacting surfaces of the guide or channel member 23 and the inside surface of the frame member 24. i

'Ihe channel or guide members23 are secured to the frame member 24 by a plurality of screws 3l which extend through suitable openings in the channel or guide members 23 and engage the fr ame members 2t. .i

It is to be noted that the side members 3- and Il, after they have been slidably moved relative to the side portions or members I6 and l1 of the end members I and 2, may be locked-in their adjusted positions by the screw V32 which extends 3 and d may be slidably and telescopically oper'-,

lated relative to the side portions i6 land lll and to provide adjustable movement so that-the upper frame assembly A may be accommodated to windows to provide the necessary lengths when the upper frame assembly A has been adjusted to t the conventional window frame of the window opening-in which the channel or guide members 23 have been assembled, the screws 32 being tightened by means of the head or handle portions 3d to hold the side'members 3 and t in y their proper assembled positions relative to their side portions it' and I7 of the end members l 'and 2. Also the Viiang'es 8 and 9 of the end portions l `and 2 may be extended to form ,overlapping edges ill inthe side members i and 2, y

as disclosed in Fig. 3, to engage the bent portions i@ ofthe anges 5 and 8 of the side portions 3 and d to'further position the side portions 3 ang. d transversely relative to the members i and After the glass assembly ii'or the screen esserti'- bly l2 has been installed in the upper 'frame assembly A, the lower side ci the upper frame sembly A is closed by the lower frame assem- The trame assembly. B comprises a sash portion et which is provided with the offset portion t@ having the. chamber til therein, the offset portion te extending toward and being adapted to engage a like odset portion di on the lower sash or frame assembly B ofthe upper frame assem bly A.

It is to be noted that the frame member @d is provided'with the side anges B2 and 42 which are extended to form the bent portions 44 and 45 in a similar manner to the side anges and 6 of the members l, 2, 3 and 4 of the upper frame or sash assembly A.

The packing or resilient materials 46 is secu to the side flanges 42 and 43 in a similar manner tothe packing materials I3, as above described. The frame member 38 is thus adapted to enclose the lower edge of the glass assembly Il or the lscreen. assembly I2, when assembled in the upper frame assembly A, the flanges 42 and 43 being adapted to be entered between theend portions y of the anges 5. and 6 of the side members 3and and and tor lock the frame assembly B against movement longitudinally of the windowiopening and to further retain the sash or iframe assembly A in an assembled position in the upper part of the guide or channel members'23, I provide the 'plungers tl which are slidably mounted in the chambers dii and between the side Walls of the frame members, such as 35, the plungers tl being of sufficient width toextend adjacent the. side surfaces of theoffset portions 33 or fil.

The plungers il are provided with the studs #it which are threadably secured in the holes d'lA of the plungers di', the studs @d being provided with the handle portions d@ to facilitate the slidable movement of the plungers di, the handle portions dt being further constructed as a nut and vtelescopically mounted in 'position` within andl between the end portions of the side members 3 threadably engaging the stud d8 to permit clampving the plungers di in their engaged or disenvided in the framemember 5t of the conventionf al .Window opening structure. v

The plungers d? are thus adapted for slidable movement in the frame member 38 so that the shouldered portions El may be entered within and removed from the holes 53.

When the shouldered portions 5i are entered within and engage the holes b3, the frame assembly B is prevented from moving longitudinally of the frame member 2t o1' the window construction. This further positions and retains the larmeans the secondary plates E5 each having a width sumcient to allow them to be'positioned in and slidably engage the side surfaces of the flange portions it and td of the members, such as Sd,

'the secondary plates 55 having a shorterlength than said main portions of the plunger-s tl so that their outer end surfaces may contact the inside surfaces of the channel or guide portions 24 and gaging positions vwith the holes 53, thus tending .to retain and maintain the frame members 3 and' 4 outwardly in positions of close contact or engagement with the inside surfaces ofv the channel portions 25 and 25A of the guide members 23.

It is to be noted that the frame assembly A is thus mounted in the channel portions 25 of the guide members 23 and at' the upper portion of the window opening in the building while the frame assembly C is mounted within the channel portions 24 of the guide members 23 and at the lower portion of the window opening in the building, as disclosed in Figs. l-and 2, the frame assembly C being substantially identical with the frame assembly A but being assembled in a reverse position so that its frame assembly D, which is constructed in a similar manner to the frame assembly B, will be inverted relative to its associated frame assembly, the offset portions 39 and 4| being positioned one above the other so that said 'offset portions 38 and 4I overlap and engage, as

disclosed in Fig. 5, the general construction of both of the frame assemblies B and D also being similar. l v

It is to be noted that the glass assembly Il will be provided with a protective and reinforcing member 56 around its peripheral edges, said protective and reinforcing material being suitably joined at its corners as disclosed at 51 in Fig. 1l,

f handling without danger of injury or chipping at its peripheral edges, the reinforcing or protective material 55 further enabling the panes of glass I I to be stored adjacent one another without danger of breakage, etc.

It is also to be noted that thescreen assembly" l2, which may be used in my window mechanism duringl the warmer months of the year, is also provided with the protective and reinforcing frame portion 58 which extends around and encloses the peripheral edges o1' the screen member I2,4 said protective and reinforcing ,frame portion 58 being joined at their corners as disclosed at 5S in Fig. 11, the protective or reinforcing frame member 58 being preferably made of light weight and-thin material such as pressed steel, aluminum, or similar material, which may be secured to the screen I2 as by welding, soldering, or simllar means.

In order to further secure the frame assemblies B and D in engagement with the sidemembers 3 and 4 of the frame assemblies A and C, the frame members 38 may be provided with the portions .60 which may b e formed by displacing aportion of the sidewall of the frame 38.to

'provide increased stock for threadably Aengaging the screws 6I, the screws 8| extending through the slotsv SIA `in one of the side walls of the flanges 6 of the frame members 3 and 4 of the frame assemblies A and C,.thus providing further and positive means, if desired, for securing the frame 38 -in .its assembled position relative to pane of glass by the remaining portions of the frame assemblies A A and C. 25 when the plungers 41 are locked in their en- Figs. 1 and 2 disclose a pair of conventional window frame assemblies 62 and S3 in which are suitably secured the panes of glass 64 and 65, the window assemblies. 62 and 63 being mounted conventionally in the channel portions of the window frame members 24 by the members 24A, said frame members 24 being mounted in conjunction with the window ledge 66 together with the apron or facing member 61 which is secured to the lower member 68 of the conventional window construction, the upper' frame member being indicated at 69 and having the front facing member 10 which is also joined to the side frame members 24. The complete conventional window construction is disclosed as -being mounted within a building constructed of bricks 1l. i

It is to be noted that my window mechanism is adapted for use not only with conventional window construction, as used in buildings constructed of brick, but is equally adapted to be used with conventional window construction in frame buildings and is further adapted for use in suc-h members as doors, etc., in which it may be desired to alternatively install window or screen members according to the seasons of the year.

In operation the guide or channel members 23 are secured in position to the longitudinal or vertical sides of the frame members 24 and then the frame assembly A is collapsed by grasping the flange portions 22 of the clips or handles 20 withv the fingers of the hand'suiciently to allow the over all width of the frame assembly A to be inserted between the minimum inside distance between the minimum inside surfaces of the guide members 23 and then with the frame assembly A opposite one of the channel portions 24 or 25, the

pressure of the fingers of the hands on the clipsV or handles 20 is released which allows thev springs 31 to expand the end members l and 2 outwardly and sidewardly so that the side portionslS and l1, together with the end members l and 2, and the side members 3 and 4 will be moved to and in close contact with the inside surfaces of the guide or channel member 23 in which the frame assembly is to be operatively assembled.

The end members l and 2 are now forced upwardly in close contact with the upper surfacev of the frame member 69, as disclosed in Fig. 2, then with the nuts loosened, the side members 3 and 4 may be adjustably moved relative to the end members I and 2 so that they will t substantially through one half the length of the window, the ability to move the end members l and 2, together with the members 3 and 4, of each of the frame assemblies A and Crendering it possible'to make the frame assembliesv A and C adjustably fit tightly around their peripheral edges in the inside channel and guide members 23 even though there are variations and tolerances between various windows, thus enabling my window mechanism to be produced in quantities and with interchangeable features rendering it easily installed in various windows with different tolerances or dimensions and resultant discrepancies in the surfaces with which my window mechanism is associated and installed.

After the frame assembly A has been itted to Athe inside surface at the top of the window structure, the glass assembly Il is inserted between the `flanges of the side members 3 and 4 and slidably moved upwardly to the position as disclosed in Fig. 3, with its peripheral edges, together with the reinforcing and protective materials thereassembly mosaics 1 V i me a pair 'or said ame' members to said side pory the various members comprised bythe trame assembly A.

The frame assembly B is now ready for installation and may be inserted between the end, portions of-side anges of the members 3 and 4 so that the lower edge of the glass assembly il is assembled therein as disclosed in Fig. 5, the packing materials 46 also being utilized to resiliently grip and position the glass assembly Il in the frame assemblies.

Thev plungers -41 are now slldably moved outwardly so 'that the shoulder portions 5l engage the .holes 53 and the screws 6I will be clamped in place to further secure the frame 38 to the side members 3, and 4 of the trame assembly.

The same procedure is followed with the frame assembly C with the exception that the frame assembly C is inverted when the frame Aassembly C has slidably moved 'downwardly to its position against the frame member 68, as disclosed in Fig. 2, the overhanging or oiset portion 4iv contacting the upper surface ofthe offset portion 39 of' the frame 33 of the frame assembly B, thus prosembly i2 being readily removable and replacel able without further removing the frame assemblies A and C from their assembled positions in the channel portions ZG'and 25 of the guide 'meinbers 23.-
